Cell analysis is an important task in both analytical and medicinal chemistry. A pilot study of capillary electrophoresis analysis of adipose stem cells is presented. The optimum conditions for cell analysis were found in morpholinoethanesulfonic acid (MES)/NaOH buffer (pH 6.0) with an addition of NaCl. Capillary electrophoresis proved to be an effective tool in analysis of adipose stem cells. It could be also used for solving many other tasks in medicinal chemistry.

Magnetoferritin is a metalloprotein composed of a protein coat (apoferritin) surrounding the magnetic iron oxide nanoparticles. Physicochemical characterization of magnetic, structural and morphological properties, size distribution and stability of magnetoferritin have been extensively investigated. Magneto-optical properties of magnetic nanoparticles in magnetoferritin can be applied in in vivo diagnosis of various diseases associated with the formation of magnetite in pathological processes in tissues. In addition, the confirmed peroxidase activity enables magnetoferritin to be used in important bioapplications. © Petr Zámostný.

The study deals with the GC-MS determination of acrylamide in various matrices. The proposed method involves bromination of acrylamide to 2,3-dibromopropanamide, its conversion to 2-bromopropenamide and the GC-MS determination. The method was used for the determination of acrylamide in water, gaseous products of combustion and in food such as potato chips and cookies. The measured concentrations of acrylamide ranged from 46 to 1980 μg kg-1 the highest levels being found in ground coffee and tobacco smoke.
